Specification of Letters Patent. Patent d, Di 16 1920 Application filed April 16. 1919. Serial No.28 019.

To e65 whom it may com-cm hnown that I, IVIICHAEL P. KEALY, a citizen of the United States, and a resident of ersey Cit-y, inthe county of Hud- 3 {State oi New Jerse h ve invented an i improved PavingBloclr, of which i ioiiowing is a hill, clear, and exact deption. v The present invention relates to new and i improvements in pavements, and permore particularly to pavements conted from wooden blocks.

' the primary object of the present invention to provide means by which the blocks are spaced with relation to each '.d means also serving to maintain in their proper position during c opv .tion of laying the pavement. Pavements of this tvpe as at present laid also present a very siwpery surface in wet weather, and it is a i r object of the present invention to space the blocks the neces rry distance to permit oi the insert of a grmit or other suitable material in sui' liciont ql'lantity to present surizue enough iv-tween the blocks to obviate this objection-- also feature.

t is a further object of the invention to provide a device of this character which is sim ale in construction and cheap of manulVith the above and other objects in view, we is to he had'to the accoinoanying .ings in which- I i are 1 is av top plan view of a portion oi" a pavement constructed in accordance with the present invention.

Fig. 2 is a perspective view of the spacing element.

Referring more specificallyto the drawings, and particularly to Fig. 1, the reference character 1G designates wooden blocks, such as those employed in laying wooden pavements, and said blocks are laid in lapjoint relation to each other with an intervening space 11 between their adjacent sides and ends.

The blocks are maintained in spaced relation to each other by means of a metallic clip 12 of special construction to particularly adapt it to this purpose. This clip 12 is substantially U-shaped and comprises a body portion 13, from which projects two parallel legs 14. As shown in Fig. 2, the body portion'13 is cut out, as at 15, to provide a projecting member 16, which extends from said her y portion 13 in a direction opposite to the legs 14. This cut-out portion extends throughout only approximately one-half oi the lateral dimension of said body portion to prevent weakening thereof,

and, at the same time, provide a projecting member which will he ca'pableof performing the function desired.

The outer or free end of each of the legs hie-ck and prevent further driving of the I spacing element 12.

When the spacing element 12 has been secured in place, the next adjacent block is placed with one of its ends in engagement ith the member 16, as shown at 20 in Fig. 1. it this system of laying the blocks is followed, it will be seen that a space .11 will be prov1ded,which space will entirely surround each respective block.

litter the several blocks have been positioned, the space 11 is filled with any suitable grout, said space being of suflicient dimensions to present a surface oi grout which will eliminate skidding and slipping on a mminent constructed as above described. l?ur-therimire, snliicient quantity of grout will be employed to permit of ready expansion of the blocks under varying conditions of moisture.

Having thus described the invention what is claimed as new is:

1. A pavement comprising a plurality of blocks laid in spaced and lap jointrelation, means carried by one of said blocks intermediate of its ends for maintaining said spaced relation, andineans carried by said spacing means and integral therewith for engaging one of the ends of one of the adjacent hlocks of said pavement, s

2. A device of the character described comprising a substantially Ushaped member. driving points formed on the free end of each of the legs of the U-shaped member, and block engaging means integral with the body portion of said U-shaped member, said block engaging means disposed at right angles to said body.

3. A device for spacing blocks eomprising a substantially U-shztped member, driving points integral with the free end of each of the legs of the U-sheped member, means integral with each of said legs and project ing at right angles thereto for limiting the i0 depth of the driving members, and block engaging means carried by the bony portion of the J-shaped member.

31:. A spacing element for blocks comprising substantially J-shaped member, block attaching means formed on the free end of each of the legs of the U-shaped member, and block engaging means integral with the body portion 01" the U-shaped member and projecting at right angles therefrom.
